➤ Wash in running water to remove powder (do not use detergent).
➤Boil for 10 mins in a pan of water to sterilise & allow to cool and dry.
➤Place in a jug and fill with tap water (charcoal may float when new but it will tend to sink after a week or so of use).
➤Leave for 8 hours or more for best results. You can leave it in the fridge to chill if you like. It's then ready to drink.
➤Re-sterilise once a week by repeating step 2.
➤ Replace with new charcoal after 2 months approx.
